Specification of Letters Patent.

Patented July 14, 1914.

Application filed September 26, 1912. Serial No. 722,397.

To all whom it may concern Be it known that I, CARL MUEI-ILEISEN, a citizen of the United States of America, residing at 23 Chausseestrasse, Berlin, N. 4, in the Empire of Germany, have invented new and useful Improvements in Typographical Casting-Machines, of which the following is a specification.

This invention relates to improvements in typographical casting machines particularly line casting machines such as those known commercially under the trade mark Linotype, in which there are provided a plurality of casting molds on one and the same rotatable mold wheel or mold carrier.

It has for its object to provide improved mechanism by which the mold wheel can be manually turned about its axis so as to bring the molds thereon into and out of op eration according to the body dimension and length of the slug required to be cast.

The invention will be best understood by reference to the accompanying drawings in which Figure l is a sectional elevation of the preferred construction of devices according to the said invention; Fig. 2 is an, edge view of the mold-wheel driving pinion; Fig. 3 is an underside view of the boss of the crank handle, with the latter shown in section, and Fig. 4 is a diagrammatic front view of the mold wheel and its driving pinion.

1 is the mold wheel carrying, in the example illustrated, two molds 2, 3 of relatively different body dimension and length, but which may be provided with more than that number.

4 is the pinion which gears with the mold wheel 1 and which, as ordinarily, is capable of being slid along its shaft 5 into and out of engagement with a driving pin 6 fast in a crank 7 rigidly secured to the shaft 5, this pin normally engaging in wellknown manner with a hole or recess 8 in the back of the pinion 4.

The pinion shaft 5 is not itself capable of longitudinal motion, and'its diameter at its forward end is less than that at its rearward end; 011 its extreme front end it has secured on it a collar 9 held thereon by a nut 10, and between the rear face of this collar and the front face of the hub 11 of the pinion there is provided a spring 12 encircling the shaft 5 and exerting its pressure on the hub 11 so as to tend always to move the pinion 4 rearward.

Upon the outer surface of the hub 11 there is mounted the boss 13 of the handle 14 this boss taking a bearing on the said surface as also upon the outer periphery of the collar 9. The hub 11 is free to rotate within the boss 13 and the latter is capable of being moved in axial direction relatively to said hub and collar 9.

The hub 11 is provided with an annular peripheral groove 15 having a tributary re- =cess 16 with which is capable of engaging a screw or stud 17 fast to, and projecting inward from, the boss 13. This boss is provided with an internal annular rib or projection 18 against which bears the rear end of a helical spring 19 which is contained within the boss 13 and surrounds the before described spring 12 and which, like that spring, bears at its outer end against the rear face of the collar 9. In the rear end of the boss 13 is formed a recess 20 adapted to engage with a stationary bracket arm or stop 21 for retaining the handle 14 against accidental displacement from its normal position in which it preferably hangs downward.

; In the normal condition of the before described apparatus the spring 12 presses the pinion 4 against the crank 7 and holds it in engagement with the crank pin 6, and the spring 19, by acting on the annular rib 18, holds the boss 13 in engagement with the stop 21 and the stud 17 out of engagement with the recess 16 and within the annular groove 15.

When it is desired to manually rotate the mold wheel 1 so as to bring say the mold 2 out of operation and the mold 3 into operation, the operator pulls forward the handle 14 so as first (against the action of the spring 19) to disengage the recess 20 from the stop 21 and engage the stud 17 with the recess 16, and then, when the stud 17 reaches the bottom of the recess 16 (against the-action of the spring 12), to move forward the pinion 4 so as to free its recess 8 from the crank pin 6. The operator then turns the handle 14 the desired number of complete revolutions,-this would be two in the arrangement shown-and thereafter allows the springs 12 and 19 to return the pinion 4 and the boss 13 to their respective normal positions, the turning of the handle 14 through the given number of complete revolutions having again brought the recesses 8 and 20 directly opposite to the crank pin 6 and stop 21 respectively, so that these recesses are thereby capable of engaging respectively with the said pin and stop.
